Nightmare Knight

Nightmare Moon has at last returned from her lunar banishment, after one-thousand years of imprisonment on the moon. Her first move was to gain revenge on Celestia, and she stood victorious after a tough battle. Celestia was banished to the moon, and in fear, many ponies did not rebel against Nightmare Moon. However, a nation was formed to overthrow Nightmare Moon, and restore Celestia's rule, even in her absence. The two nations were named "The Lunar Kingdom" and "The New Solar Republic". These nations fought over Equestria, attack after attack.
